Product features:
1. Slient check valve with "bullet head" and "waist drum" shape design, which improve medium flow direction and reduce the flow resistance coefficient.
2. Slient check valve with short structure make it small size and lower manufacturing cost.
3. Slient check valve equipped with non-metallic lubrication sleeve between the guide shaft and the guide frame, the valve disc can be lifted and lowered flexibly without any locking phenomenon.
4. The skeleton type rubber sealing ring is directly embedded on the valve body, avoiding direct erosion of the sealing ring by the medium for a long time, significantly extending its service life, and being sturdy and durable.
5. The short opening and closing stroke of the valve disc can effectively prevent water hammer.
6. Suitable for fire fighting system, water supply, drainage systems, high-rise building pipe networks, and can be installed at the outlet of pumps as a suction bottom valve.
